  "prompt": "Genre: Pop-Rock, Alternative Pop; BPM: 130; Key: G# major; Rhythm: Driving eighth-note rock groove with a syncopated, slightly overdriven bassline creating a tight rhythmic pocket. The kick is heavy on beats 1 and 3, with a sharp snare on 2 and 4.; Instruments: Acoustic kit; tight-mic'd snare, punchy kick, controlled room. P-bass with a pick; slight overdrive, prominent low-mids. Layered electrics; clean arpeggiated Telecaster, overdriven power chords; Vocals: Female, starting with an intimate close-mic delivery in the verses, building to powerful chest belting in the chorus, supported by lush background vocal stacks.; Mood: The feeling of your stomach dropping on a rollercoaster, mixed with the electric buzz of seeing your crush walk into the room, your heart pounding so loud you can hear it in your ears.; Highlight: The explosive drum fill and guitar swell launching out of the tense bridge into the final, full-band chorus, creating a massive dynamic release.",

  "lyrics": "[verse]\n(Chords: G# - D# - Fm - C#)\n(Mix: Centered and focused. Vocal is dry and upfront. Guitars are clean and panned mid-left/right. Drums are punchy and tight with minimal room sound. Bass sits right in the middle, locked with the kick.)\n(Inst: Clean arpeggiated electric guitar; Driving picked bass; Tight acoustic drum kit)\n(Vocal-Perf: Conversational, breathy, close-mic'd intimacy)\n(Melody-Contour: Narrow melodic range, mostly stepwise motion, creating a spoken-sung feel)\n(Melody-Rhythm: Phrases often start on the upbeat of 1, syncopated against the driving beat)\nYou borrowed my lighter two Tuesdays ago\nAnd I keep finding reasons to come by your door\nI traced where the hallway paint starts to go thin\nAbove the third step where you always lean in\nOhh\n\n[chorus]\n(Chords: G# - D# - Fm - C#)\n(Mix: Explodes in stereo width. Guitars are hard-panned. Parallel compression added to drums and lead vocal for size and punch.)\n(Inst: Adds layered, overdriven power-chord guitars; Crashing cymbals; Bassline becomes more active)\n(Vocal-Perf: Shifts to powerful chest-voice belting; Lush background vocal stacks enter, wide-panned)\n(Hook-DNA: Syncopated 16th-note vocal pickup into a driving rhythmic phrase anchoring on the 3rd and 5th; Motif repeats twice, with the third statement altered for tension)\n(Melody-Harmonic-Tension: High, sustained notes held over the V chord create a powerful sense of anticipation before resolving stepwise down to the tonic chord)\nI practiced being easy, being cool\nBut my ribcage cracked before I crossed the room\nThese fault lines run right through my chest\nEvery crack maps back to your address\nI tried to hold the ceiling up alone\nNow the whole thing shakes when you come home\nSomething in me I can't get back\nBut fall apart and I might find the crack\n\n[verse]\n(Chords: G# - D# - Fm - C#)\n(Mix: Narrows slightly from chorus but maintains higher energy than verse 1)\n(Inst: A secondary, slightly delayed guitar line is added for texture)\n(Vocal-Perf: Retains intimate tone but with more urgency and attitude)\n(Melody-Rhythm: More percussive and rhythmically complex phrasing)\nMy shoulder blade still knows the wall by your stairs\nThe cold plaster, January air\nYou said something like \"you always overthink\"\nAnd every nerve in my body agreed\nI've been rehearsing exits since the fall\nLeft-hand door, three seconds, down the hall\nBut here I am\nStuck at the threshold again, waiting on you\nLike does your voice drop when you're nervous too?\nDo you rehearse lines in the shower at noon?\nI've been unraveling threads from the sleeve\nOf every quiet thing I need you to see, goddamn\nAnd maybe we could break the careful ground\nKnees buckle, walls come tumbling down\nFault lines\nOpening up beneath us now\n\n[bridge]\n(Chords: C# - G# - D# - D#)\n(Mix: Dynamic drop. Instruments are pushed back with more reverb and space. Vocal becomes the primary focus.)\n(Inst: Guitars become atmospheric with delay/reverb; Bass and drums simplify to a tense, pulsing heartbeat rhythm)\n(Vocal-Perf: Starts soft and contemplative, builds in intensity and pitch into the final chorus)\n(Melody-Harmonic-Tension: Melody deliberately avoids resolution, ending each phrase on the 2nd or 7th over sustained chords, creating a floating, unresolved tension that begs for the release of the chorus)\nI keep measuring the distance\nBetween what I'll say and what I mean\nEvery inch is a resistance\nTo the thing that's splitting me\nI keep measuring the distance\nBetween what I'll say and what I mean\nEvery inch is a resistance\nAnd it's splitting everything\n\n[chorus]\n(Chords: G# - D# - Fm - C#)\n(Mix: The biggest and widest point of the track. All elements pushed forward. Vocal ad-libs panned dynamically.)\n(Inst: Maximum layers. Drum fills are more frequent and complex. Guitars are thick and powerful.)\n(Vocal-Perf: Full power belt with passionate ad-libs and overlapping vocal harmonies)\n(Transition: Explosive drum fill and guitar swell launches into the section)\nOhh\nI practiced being easy, being cool\nBut my ribcage cracked before I crossed the room\nThese fault lines run right through my chest\nEvery crack maps back to your address\nI tried to hold the ceiling up alone\nNow the whole thing shakes when you come home\nSomething in me I can't get back\nBut fall apart and I might\n\n[outro]\n(Chords: G#)\n(Mix: Abruptly cuts to a more intimate space on the final line.)\n(Inst: Final, sustained power chord from the full band which rings out)\n(Vocal-Perf: Final phrases delivered with a mix of power and breathy exhaustion)\nFall apart and I might\nFall apart and I might find the crack",
  "cover_prompt": "生成一张无字音乐专辑封面。风格严格参照 20 世纪 Color Field Painting（色域绘画），如 Mark Rothko 晚期作品的色层叠压逻辑与 Helen Frankenthaler 的浸染法（soak-stain technique）。画面的核心色彩与情绪：深裂岩红与哑光骨白之间的张力渐变——底层是一片被压制的、沉重的赤褐红（如干涸土地在高压下的颜色），向上渗透为撕裂状的骨白与冷灰交界，边缘如混凝土断面裂开后露出的内芯，带有一种压抑与爆发前的静止感。\n技法要求：色彩之间的过渡必须模拟颜料在未上浆的粗纹棉布（raw cotton canvas）上自然渗透、晕开的效果，边界柔软但保留颜料浓度不均匀造成的自然深浅变化（pigment pooling）。画面需要呈现真实画布的编织肌理（woven canvas texture），局部可见稀薄处透出的底布纹路。整体色调偏低饱和、微微发灰（muted, desaturated palette），避免荧光感和数字渐变的均匀平滑。\n绝对禁止：任何文字/字母/拼音、人物或人物轮廓、具象物体、几何图案、锐利边缘、胶片颗粒滤镜、3D渲染质感。",
